Sound insulation barrier for transformer or converter transformer and sound insulation transformer or converter transformer

The utility model relates to the field of transformer substations and converter stations, discloses a sound insulation barrier for a transformer or a converter transformer and the sound insulation transformer or the converter transformer, and can effectively reduce low-frequency noise generated in the working process of the transformer or the converter transformer. The sound insulation barrier comprises a steel stand column and a plurality of photovoltaic sound absorption and insulation components. The photovoltaic sound absorption and insulation component comprises a photovoltaic assembly, a first sound absorption panel, two fixed side plates and two fixed bottom plates. The photovoltaic assembly is a transparent screen body which converts light energy into electric energy and is perpendicular to the ground, the two sides of the short edge are connected with the fixed side plates, and the two sides of the long edge are connected with the fixed bottom plate. The first sound absorption panel is parallel to the
